Words don’t change. But in many languages, one word has many forms:
English: The man is blind.German: Der Mann ist blind.
English: This is a blind man.German: Das ist ein blinder Mann.
English: I see a blind man.German: Ich sehe einen blinden Mann

Call everybody “you”. You can say “Do you speak English?” to your friend or to your teacher. In other languages, you have to use the right word for the right person. In English, everybody is equal. 🙂

English is everywhere. You can easily access English-language television, music, websites, magazines, etc. You don’t have to learn from boringtextbooks. You can learn and use your English at the same time. Using your English is especially important because it increases your desire to learn.
